COLLAPSIBLE KNOCKDOWN BOX.

Specification of Letters Yatent.

Patented Jan. 18, 1910.

To all whom 'it may concern:

lie it known that, I, CHARLES Farmers .iti) kiss. a citizen of the United States, rcllllllg at Washington. in the District of ('olumhia. have invented certain new and useful improvements in Collapsible Knock down Boxes: and I do hereby declare the following: to he a full. clear, and exact do rriplion oi the invention, such as will onahhaolhers skilled in the art to which it apprrtains to make and use the same.

This invention relates to collapsible knockdown boxes, and has for its object to iilwtllllt surh a box. the blank of which can he readily stamped out of paper and which hlanl; will involve a minimum of waste after it is rut into shape.

To these ends the invention consists in the novel details of construction and combination of parts more fully hereinafter disclosed and particularly pointed out in the rluiins.

Referring to the arcompanyiug drawings forming a part of this specification. in which.

like numerals refer to like parts in all the vic\\'s;-l igure 1, is a perspective elevational view of the completed box: Fig. .2, is -a perspective view showing the box in its knockdown or collapsed condition; Fig. 3. is a plan view of the blank from which the lJHXt: are made; and, Fig. l, is a pers ective view showing the blank partially to dcd to form the completed box.

The blank from which the box is made is composed of a series of panels 1, having integral therewith a series. of narrower panels '2, separated from said panels 1 by weakened or scored lines 3' and provided near one end with triangular notches or holes 4, leaving a space 5 between the bottom of said notches and the edge U-of the blank. .\t one end of the blank a flap 7 is attached to one of the panels 2, and at the other end of the blank a. bottom 8 is separated from one of the wider panels by a comparatively narrow open slot, 9, having an L-shaped extension In, at one end. The material under the L portion of-this slot is bent away from the hollow. as shown in Fig. l, to leave the projl-rting worm-r 18 there illustrated. The sa id hollom 8 is integrally attached to the Ilangod strip ll, which. in turn. is integrally attached lo the adjari-nl panel l, and weakened line 12 is provided where it joins the folded along the with said panel. The outer end of said strip 11 is cut away to form the rectangular space 125 and to provide the projecting corner 17 on the bottom 8, as illustrated. The strip 11 is of the saint: width as the portions 5 extending, beneath the triangular perform tions 4.

in assembling the box, the bottom 8 is firstline 14- at right angles to the strip 11, as illustrated in Fig. 4. The strip 11 and bottom 8 are then folded at. right angles to the adjacent panel 1, alon the. line 12. and then the corners in, 16,1111 1?, of the bottom are successively inserted in the triangular perforations 4, as the panels 1 and 2 are wrapped around the said bottom. The last perforation 4 next to the flap T will fold over the corner in of the bottom, and the said llap 7 will, thereupon, overlap the panel 1 next to the bottom, as shown in Fig. 3, and said flap 7 is, thereupon, secured to said last, mentioned panel by staples 19, or other suitable fastenings.

After the flap T has been secured to the body portion of the box, by pressing up wardly on the bottom 5, the corners thereof will readily disengage from the perforations 4, owing to their triangular shape, and althou h the body portion of the box is in a tubu ar form. yet. the same may be readily collapsed, as shown in Fig. 2, with the bot tom occupying the position shown. In this position the box occupies a small space and can be readily packed ccunulnii-ally for shipping. When it is desired to open out the box, it. is only necessary to open out, the tubular l|()tl portion and lo then tori-e the bottom down into position. when its corners will readily take into the triangular perforations 4 and seat themselves, as shown in Fig. 1. This action is greatly facilitated by the upwardly pointed, triangular, shape of said perforations 4, and the bottom, of course, in

(ill

such action, hinges on the line 14-, best shown I n sp between the bottom of said perfora wider corner 18 on said bottom; a narrow strip rrectien in Letters- Rat'eni No. 947,179.

integrally attached to said bottom, of a less length than the width of said bottom to form a corner 17 on the latter, said strip being integrally attached to one of said Wider panels; sibstantially as described.

ity of wide and narrow panels integral with each other, the narrow panels provided with triangular-she ed perforations near one end, and one of sai panels provided with a flap; a narrow strip integral with one of said [SEAL] knockdown and collapsible box formed from a paper blank having a plural ,ture, in presence panels and of a less length than the width of said bottom to form a corner 17, a bottom integral with said strip, and separated from one of said wider panels by an L-shaped slot to form a corner 18 on said bottom and suitable fastenings between said flap, and one of said wider panels, whereby the bottom of the box may be readily unseated and the box collapsed for shipping, or may be readily seated, when the box is intended for use; substantially as described.

In testimony whereof, I afiix my signaof two witnesses.
